FIELD OF THE INVENTION

The present invention relates to the field of plant breeding and, morespecifically, to the development of tomato hybrid SVTE7216 and tomatoline FDS-XJ16-6057.

BACKGROUND OF THE INVENTION

The goal of vegetable breeding is to combine various desirable traits ina single variety. Such desirable traits may include any trait deemedbeneficial or desirable by a grower or consumer, including greateryield, resistance to insects or disease, tolerance to environmentalstress, and nutritional value.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same plant or plant variety. A plant cross-pollinates if pollencomes to it from a flower of a different plant variety.

Plants that have been self-pollinated and selected for type over manygenerations become homozygous at almost all genetic loci and produce auniform population of true breeding progeny, a homozygous plant. A crossbetween two such homozygous plants of different genotypes produces auniform population of hybrid plants that are heterozygous for manygenetic loci. Conversely, a cross of two plants each heterozygous at anumber of loci produces a population of hybrid plants that differgenetically and are not uniform. The resulting non-uniformity makesperformance unpredictable.

The development of uniform varieties requires the development ofhomozygous inbred plants, the crossing of these inbred plants, and theevaluation of the crosses. Pedigree breeding and recurrent selection areexamples of breeding methods that have been used to develop inbredplants from breeding populations. Those breeding methods combine thegenetic backgrounds from two or more plants or various other broad-basedsources into breeding pools from which new lines and hybrids derivedtherefrom are developed by selfing and selection of desired phenotypes.The new lines and hybrids are evaluated to determine which of those havecommercial potential.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides a tomato plant of hybridSVTE7216 or line FDS-XJ16-6057. Also provided are tomato plants havingall the physiological and morphological characteristics of such a plant.Parts of these tomato plants are also provided, for example, includingpollen, an ovule, an embryo, a seed, a scion, a rootstock, a fruit, anda cell of the plant.

In another aspect of the invention, a plant of tomato hybrid SVTE7216 ortomato line FDS-XJ16-6057 comprising an added heritable trait isprovided. The heritable trait may comprise a genetic locus that is, forexample, a dominant or recessive allele. In one embodiment of theinvention, a plant of tomato hybrid SVTE7216 or tomato lineFDS-XJ16-6057 is defined as comprising a single locus conversion. Inspecific embodiments of the invention, an added genetic locus confersone or more traits such as, for example, herbicide tolerance, insectresistance, disease resistance, and modified carbohydrate metabolism. Infurther embodiments, the trait may be conferred by a naturally occurringgene introduced into the genome of a line by backcrossing, a natural orinduced mutation, or a transgene introduced through genetictransformation techniques into the plant or a progenitor of any previousgeneration thereof. When introduced through transformation, a geneticlocus may comprise one or more genes integrated at a single chromosomallocation.

In some embodiments, a single locus conversion includes one or moresite-specific changes to the plant genome, such as, without limitation,one or more nucleotide modifications, deletions, or insertions. A singlelocus may comprise one or more genes or nucleotides integrated ormutated at a single chromosomal location. In one embodiment, a singlelocus conversion may be introduced by a genetic engineering technique,methods of which include, for example, genome editing with engineerednucleases (GEEN) Engineered nucleases include, but are not limited to,Cas endonucleases; zinc finger nucleases (ZFNs); transcriptionactivator-like effector nucleases (TALENs); engineered meganucleases,also known as homing endonucleases; and other endonucleases for DNA orRNA-guided genome editing that are well-known to the skilled artisan.

The invention also concerns the seed of tomato hybrid SVTE7216 or tomatoline FDS-XJ16-6057. The seed of the invention may be provided as anessentially homogeneous population of seed of tomato hybrid SVTE7216 ortomato line FDS-XJ16-6057. Essentially homogeneous populations of seedare generally free from substantial numbers of other seed. Therefore,seed of tomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 may bedefined as forming at least about 97% of the total seed, including atleast about 98%, 99%, or more of the seed. The seed population may beseparately grown to provide an essentially homogeneous population oftomato plants designated SVTE7216 or FDS-XJ16-6057.

In yet another aspect of the invention, a tissue culture of regenerablecells of a tomato plant of hybrid SVTE7216 or tomato line FDS-XJ16-6057is provided. The tissue culture will preferably be capable ofregenerating tomato plants capable of expressing all of thephysiological and morphological characteristics of the starting plantand of regenerating plants having substantially the same genotype as thestarting plant. Examples of some of the physiological and morphologicalcharacteristics of tomato hybrid SVTE7216 or tomato line FDS-XJ16-6057include those traits set forth in the tables herein. The regenerablecells in such tissue cultures may be derived, for example, from embryos,meristems, cotyledons, pollen, leaves, anthers, roots, root tips,pistils, flowers, seed, and stalks. Still further, the present inventionprovides tomato plants regenerated from a tissue culture of theinvention, the plants having all the physiological and morphologicalcharacteristics of tomato hybrid SVTE7216 or tomato line FDS-XJ16-6057.

In still yet another aspect of the invention, processes are provided forproducing tomato seeds, plants, and fruit, which processes generallycomprise crossing a first parent tomato plant with a second parenttomato plant, wherein at least one of the first or second parent plantsis a plant of tomato line FDS-XJ16-6057. These processes may be furtherexemplified as processes for preparing hybrid tomato seed or plants,wherein a first tomato plant is crossed with a second tomato plant of adifferent, distinct genotype to provide a hybrid that has, as one of itsparents, a plant of tomato line FDS-XJ16-6057. In these processes,crossing will result in the production of seed. The seed productionoccurs regardless of whether the seed is collected or not.

In one embodiment of the invention, the first step in “crossing”comprises planting seeds of a first and second parent tomato plant,often in proximity so that pollination will occur for example, mediatedby insect vectors. Alternatively, pollen can be transferred manually.Where the plant is self-pollinated, pollination may occur without theneed for direct human intervention other than plant cultivation.

A second step may comprise cultivating or growing the seeds of first andsecond parent tomato plants into plants that bear flowers. A third stepmay comprise preventing self-pollination of the plants, such as byemasculating the flowers (i.e., killing or removing the pollen).

A fourth step for a hybrid cross may comprise cross-pollination betweenthe first and second parent tomato plants. Yet another step comprisesharvesting the seeds from at least one of the parent tomato plants. Theharvested seed can be grown to produce a tomato plant or hybrid tomatoplant.

The present invention also provides the tomato seeds and plants producedby a process that comprises crossing a first parent tomato plant with asecond parent tomato plant, wherein at least one of the first or secondparent tomato plants is a plant of tomato hybrid SVTE7216 or tomato lineFDS-XJ16-6057. In one embodiment of the invention, tomato seed andplants produced by the process are first generation (F₁) hybrid tomatoseed and plants produced by crossing a plant in accordance with theinvention with another, distinct plant. The present invention furthercontemplates plant parts of such an F₁ hybrid tomato plant, and methodsof use thereof. Therefore, certain exemplary embodiments of theinvention provide an F₁ hybrid tomato plant and seed thereof.

In still yet another aspect, the present invention provides a method ofproducing a plant derived from tomato hybrid SVTE7216 or tomato lineFDS-XJ16-6057, the method comprising the steps of: (a) preparing aprogeny plant derived from tomato hybrid SVTE7216 or tomato lineFDS-XJ16-6057, wherein said preparing comprises crossing a plant oftomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 with a second plant;and (b) crossing the progeny plant with itself or a second plant toproduce a seed of a progeny plant of a subsequent generation. In furtherembodiments, the method may additionally comprise: (c) growing a progenyplant of a subsequent generation from said seed of a progeny plant of asubsequent generation and crossing the progeny plant of a subsequentgeneration with itself or a second plant; and repeating the steps for anadditional 3-10 generations to produce a plant derived from tomatohybrid SVTE7216 or tomato line FDS-XJ16-6057. The plant derived fromtomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 may be an inbredline, and the aforementioned repeated crossing steps may be defined ascomprising sufficient inbreeding to produce the inbred line. In themethod, it may be desirable to select particular plants resulting fromstep (c) for continued crossing according to steps (b) and (c). Byselecting plants having one or more desirable traits, a plant derivedfrom tomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 is obtainedwhich possesses some of the desirable traits of the line/hybrid as wellas potentially other selected traits.

In certain embodiments, the present invention provides a method ofproducing food or feed comprising: (a) obtaining a plant of tomatohybrid SVTE7216 or tomato line FDS-XJ16-6057, wherein the plant has beencultivated to maturity, and (b) collecting at least one tomato from theplant.

In still yet another aspect of the invention, the genetic complement oftomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 is provided. Thephrase “genetic complement” is used to refer to the aggregate ofnucleotide sequences, the expression of which sequences defines thephenotype of, in the present case, a tomato plant, or a cell or tissueof that plant. A genetic complement thus represents the genetic makeupof a cell, tissue or plant, and a hybrid genetic complement representsthe genetic make-up of a hybrid cell, tissue or plant. The inventionthus provides tomato plant cells that have a genetic complement inaccordance with the tomato plant cells disclosed herein, and seeds andplants containing such cells.

Plant genetic complements may be assessed by genetic marker profiles,and by the expression of phenotypic traits that are characteristic ofthe expression of the genetic complement, e.g., isozyme typing profiles.It is understood that tomato hybrid SVTE7216 or tomato lineFDS-XJ16-6057 could be identified by any of the many well-knowntechniques such as, for example, Simple Sequence Length Polymorphisms(SSLPs) (Williams et al., Nucleic Acids Res., 1 8:6531-6535, 1990),Randomly Amplified Polymorphic DNAs (RAPDs), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified FragmentLength Polymorphisms (AFLPs) (EP 534 858, specifically incorporatedherein by reference in its entirety), and Single NucleotidePolymorphisms (SNPs) (Wang et al., Science, 280:1077-1082, 1998).

In still yet another aspect, the present invention provides hybridgenetic complements, as represented by tomato plant cells, tissues,plants, and seeds, formed by the combination of a haploid geneticcomplement of a tomato plant of the invention with a haploid geneticcomplement of a second tomato plant, preferably, another, distincttomato plant. In another aspect, the present invention provides a tomatoplant regenerated from a tissue culture that comprises a hybrid geneticcomplement of this invention.

C. Breeding Tomato Plants

One aspect of the current invention concerns methods for producing seedof tomato hybrid SVTE7216 involving crossing tomato line FDRXJ14-7092and tomato line FDS-XJ16-6057. Alternatively, in other embodiments ofthe invention, tomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 maybe crossed with itself or with any second plant. Such methods can beused for propagation of tomato hybrid SVTE7216 or tomato lineFDS-XJ16-6057 or can be used to produce plants that are derived fromtomato hybrid SVTE7216 or tomato line FDS-XJ16-6057. Plants derived fromtomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 may be used, incertain embodiments, for the development of new tomato varieties.

The development of new varieties using one or more starting varieties iswell-known in the art. In accordance with the invention, novel varietiesmay be created by crossing tomato hybrid SVTE7216 followed by multiplegenerations of breeding according to such well-known methods. Newvarieties may be created by crossing with any second plant. In selectingsuch a second plant to cross for the purpose of developing novel lines,it may be desired to choose those plants which either themselves exhibitone or more selected desirable characteristics or which exhibit thedesired characteristic(s) when in hybrid combination. Once initialcrosses have been made, inbreeding and selection take place to producenew varieties. For development of a uniform line, often five or moregenerations of selfing and selection are involved.

Uniform lines of new varieties may also be developed by way ofdouble-haploids. This technique allows the creation of true breedinglines without the need for multiple generations of selfing andselection. In this manner true breeding lines can be produced in aslittle as one generation. Haploid embryos may be produced frommicrospores, pollen, anther cultures, or ovary cultures. The haploidembryos may then be doubled autonomously, or by chemical treatments(e.g., colchicine treatment). Alternatively, haploid embryos may begrown into haploid plants and treated to induce chromosome doubling. Ineither case, fertile homozygous plants are obtained. In accordance withthe invention, any of such techniques may be used in connection with aplant of the invention and progeny thereof to achieve a homozygous line.

Backcrossing can also be used to improve an inbred plant. Backcrossingtransfers a specific desirable trait from one inbred or non-inbredsource to an inbred that lacks that trait. This can be accomplished, forexample, by first crossing a superior inbred (A) (recurrent parent) to adonor inbred (non-recurrent parent), which carries the appropriate locusor loci for the trait in question. The progeny of this cross are thenmated back to the superior recurrent parent (A) followed by selection inthe resultant progeny for the desired trait to be transferred from thenon-recurrent parent. After five or more backcross generations withselection for the desired trait, the progeny have the characteristicbeing transferred, but are like the superior parent for most or almostall other loci. The last backcross generation would be selfed to givepure breeding progeny for the trait being transferred.

The plants of the present invention are particularly well suited for thedevelopment of new lines based on the elite nature of the geneticbackground of the plants. In selecting a second plant to cross withtomato hybrid SVTE7216 or tomato line FDS-XJ16-6057 for the purpose ofdeveloping novel tomato lines, it will typically be preferred to choosethose plants which either themselves exhibit one or more selecteddesirable characteristics or which exhibit the desired characteristic(s)when in hybrid combination. Examples of desirable traits may include, inspecific embodiments, high seed yield, high seed germination, seedlingvigor, high fruit yield, disease tolerance or resistance, andadaptability for soil and climate conditions. Consumer-driven traits,such as a fruit shape, color, texture, and taste are other examples oftraits that may be incorporated into new lines of tomato plantsdeveloped by this invention.

Delayed fruit ripening is a trait that is especially desirable in tomatoproduction, in that it provides a number of important benefits includingan increase in fruit shelf life, the ability to transport fruit longerdistances, the reduction of spoiling of fruit during transport orstorage, and an increase in the flexibility of harvest time. The abilityto delay harvest is especially useful for the processing industry astomato fruits may be picked in a single harvest. A number of genes havebeen identified as playing a role in fruit ripening in tomato. Mutationsin some of these genes were observed to be correlated with an extendedshelf life phenotype (Garg et al., Adv. Hort. Sci. 22: 54-62, 2008). Forexample, WO2010042865 discloses that certain mutations in the 2nd or 3rdexon in the non-ripening (NOR) gene can result in extended shelf lifephenotypes. These mutations are believed to result in an early stopcodon. It is therefore expected that any mutation resulting in an earlystop codon in an exon in the NOR gene, particularly a mutation resultingin an early stop codon in the 3rd exon, will result in a slower ripeningor an extended shelf life phenotype in tomato. A marker to select forthe unique mutation of each allele and to distinguish between thedifferent alleles of the NOR gene in a breeding program can be developedby methods known in the art.

D. Further Embodiments of the Invention

In certain aspects of the invention, plants described herein areprovided modified to include at least a first desired heritable trait.Such plants may, in one embodiment, be developed by a plant breedingtechnique called backcrossing, wherein essentially all of themorphological and physiological characteristics of a variety arerecovered in addition to a genetic locus transferred into the plant viathe backcrossing technique. The term single locus converted plant asused herein refers to those tomato plants which are developed by a plantbreeding technique called backcrossing or by genetic engineering,wherein essentially all of the morphological and physiologicalcharacteristics of a variety are recovered or conserved in addition tothe single locus introduced into the variety via the backcrossing orgenetic engineering technique, respectively. By essentially all of themorphological and physiological characteristics, it is meant that thecharacteristics of a plant are recovered or conserved that are otherwisepresent when compared in the same environment, other than an occasionalvariant trait that might arise during backcrossing, introduction of atransgene, or application of a genetic engineering technique.

Backcrossing methods can be used with the present invention to improveor introduce a characteristic into the present variety. The parentaltomato plant which contributes the locus for the desired characteristicis termed the nonrecurrent or donor parent. This terminology refers tothe fact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental tomato plant towhich the locus or loci from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol.

In a typical backcross protocol, the original variety of interest(recurrent parent) is crossed to a second variety (nonrecurrent parent)that carries the single locus of interest to be transferred. Theresulting progeny from this cross are then crossed again to therecurrent parent and the process is repeated until a tomato plant isobtained wherein essentially all of the morphological and physiologicalcharacteristics of the recurrent parent are recovered in the convertedplant, in addition to the single transferred locus from the nonrecurrentparent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single locus of the recurrent variety ismodified or substituted with the desired locus from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphologicalconstitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some commercially desirable trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered and the genetic distance between the recurrentand nonrecurrent parents. Although backcrossing methods are simplifiedwhen the characteristic being transferred is a dominant allele, arecessive allele, or an additive allele (between recessive anddominant), may also be transferred. In this instance it may be necessaryto introduce a test of the progeny to determine if the desiredcharacteristic has been successfully transferred.

In one embodiment, progeny tomato plants of a backcross in which a plantdescribed herein is the recurrent parent comprise (i) the desired traitfrom the non-recurrent parent and (ii) all of the physiological andmorphological characteristics of tomato the recurrent parent asdetermined at the 5% significance level when grown in the sameenvironmental conditions.

New varieties can also be developed from more than two parents. Thetechnique, known as modified backcrossing, uses different recurrentparents during the backcrossing. Modified backcrossing may be used toreplace the original recurrent parent with a variety having certain moredesirable characteristics or multiple parents may be used to obtaindifferent desirable characteristics from each.

With the development of molecular markers associated with particulartraits, it is possible to add additional traits into an established germline, such as represented here, with the end result being substantiallythe same base germplasm with the addition of a new trait or traits.Molecular breeding, as described in Moose and Mumm, 2008 (PlantPhysiol., 147: 969-977), for example, and elsewhere, provides amechanism for integrating single or multiple traits or QTL into an eliteline. This molecular breeding-facilitated movement of a trait or traitsinto an elite line may encompass incorporation of a particular genomicfragment associated with a particular trait of interest into the eliteline by the mechanism of identification of the integrated genomicfragment with the use of flanking or associated marker assays. In theembodiment represented here, one, two, three or four genomic loci, forexample, may be integrated into an elite line via this methodology. Whenthis elite line containing the additional loci is further crossed withanother parental elite line to produce hybrid offspring, it is possibleto then incorporate at least eight separate additional loci into thehybrid. These additional loci may confer, for example, such traits as adisease resistance or a fruit quality trait. In one embodiment, eachlocus may confer a separate trait. In another embodiment, loci may needto be homozygous and exist in each parent line to confer a trait in thehybrid. In yet another embodiment, multiple loci may be combined toconfer a single robust phenotype of a desired trait.

Many single locus traits have been identified that are not regularlyselected for in the development of a new inbred but that can be improvedby backcrossing techniques. Single locus traits may or may not betransgenic; examples of these traits include, but are not limited to,herbicide resistance, resistance to bacterial, fungal, or viral disease,insect resistance, modified fatty acid or carbohydrate metabolism, andaltered nutritional quality. These comprise genes generally inheritedthrough the nucleus.

Direct selection may be applied where the single locus acts as adominant trait. For this selection process, the progeny of the initialcross are assayed for viral resistance or the presence of thecorresponding gene prior to the backcrossing. Selection eliminates anyplants that do not have the desired gene and resistance trait, and onlythose plants that have the trait are used in the subsequent backcross.This process is then repeated for all additional backcross generations.

Selection of tomato plants for breeding is not necessarily dependent onthe phenotype of a plant and instead can be based on geneticinvestigations. For example, one can utilize a suitable genetic markerwhich is closely genetically linked to a trait of interest. One of thesemarkers can be used to identify the presence or absence of a trait inthe offspring of a particular cross, and can be used in selection ofprogeny for continued breeding. This technique is commonly referred toas marker assisted selection. Any other type of genetic marker or otherassay which is able to identify the relative presence or absence of atrait of interest in a plant can also be useful for breeding purposes.Procedures for marker assisted selection are well known in the art. Suchmethods will be of particular utility in the case of recessive traitsand variable phenotypes, or where conventional assays may be moreexpensive, time consuming, or otherwise disadvantageous. In addition,marker assisted selection may be used to identify plants comprisingdesirable genotypes at the seed, seedling, or plant stage, to identifyor assess the purity of a cultivar, to catalog the genetic diversity ofa germplasm collection, and to monitor specific alleles or haplotypeswithin an established cultivar.

Types of genetic markers which could be used in accordance with theinvention include, but are not necessarily limited to, Simple SequenceLength Polymorphisms (SSLPs) (Williams et al., Nucleic Acids Res., 18:6531-6535, 1990), Randomly Amplified Polymorphic DNAs (RAPDs), DNAAmplification Fingerprinting (DAF), Sequence Characterized AmplifiedRegions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR),Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858,specifically incorporated herein by reference in its entirety), andSingle Nucleotide Polymorphisms (SNPs) (Wang et al., Science,280:1077-1082, 1998).

In particular embodiments of the invention, marker assisted selection isused to increase the efficiency of a backcrossing breeding scheme forproducing a tomato line comprising a desired trait. This technique iscommonly referred to as marker assisted backcrossing (MABC). Thistechnique is well-known in the art and may involve, for example, the useof three or more levels of selection, including foreground selection toidentity the presence of a desired locus, which may complement orreplace phenotype screening protocols; recombinant selection to minimizelinkage drag; and background selection to maximize recurrent parentgenome recovery.

E. Plants Derived by Genetic Engineering

Various genetic engineering technologies have been developed and may beused by those of skill in the art to introduce traits in plants. Incertain aspects of the claimed invention, traits are introduced intotomato plants via altering or introducing a single genetic locus ortransgene into the genome of a recited variety or progenitor thereof.Methods of genetic engineering to modify, delete, or insert genes andpolynucleotides into the genomic DNA of plants are well-known in theart.

In specific embodiments of the invention, improved tomato lines can becreated through the site-specific modification of a plant genome.Methods of genetic engineering include, for example, utilizingsequence-specific nucleases such as zinc-finger nucleases (see, forexample, U.S. Pat. Appl. Pub. No. 2011-0203012); engineered or nativemeganucleases; TALE-endonucleases (see, for example, U.S. Pat. Nos.8,586,363 and 9,181,535); and RNA-guided endonucleases, such as those ofthe CRISPR/Cas systems (see, for example, U.S. Pat. Nos. 8,697,359 and8,771,945 and U.S. Pat. Appl. Pub. No. 2014-0068797). One embodiment ofthe invention thus relates to utilizing a nuclease or any associatedprotein to carry out genome modification. This nuclease could beprovided heterologously within donor template DNA for templated-genomicediting or in a separate molecule or vector. A recombinant DNA constructmay also comprise a sequence encoding one or more guide RNAs to directthe nuclease to the site within the plant genome to be modified. Furthermethods for altering or introducing a single genetic locus include, forexample, utilizing single-stranded oligonucleotides to introduce basepair modifications in a tomato plant genome (see, for example Sauer etal., Plant Physiol, 170(4):1917-1928, 2016).

Methods for site-directed alteration or introduction of a single geneticlocus are well-known in the art and include those that utilizesequence-specific nucleases, such as the aforementioned, or complexes ofproteins and guide-RNA that cut genomic DNA to produce a double-strandbreak (DSB) or nick at a genetic locus. As is well-understood in theart, during the process of repairing the DSB or nick introduced by thenuclease enzyme, a donor template, transgene, or expression cassettepolynucleotide may become integrated into the genome at the site of theDSB or nick. The presence of homology arms in the DNA to be integratedmay promote the adoption and targeting of the insertion sequence intothe plant genome during the repair process through homologousrecombination or non-homologous end joining (NHEJ).

In another embodiment of the invention, genetic transformation may beused to insert a selected transgene into a plant of the invention ormay, alternatively, be used for the preparation of transgenes which canbe introduced by backcrossing. Methods for the transformation of plantsthat are well-known to those of skill in the art and applicable to manycrop species include, but are not limited to, electroporation,microprojectile bombardment, Agrobacterium-mediated transformation, anddirect DNA uptake by protoplasts.

To effect transformation by electroporation, one may employ eitherfriable tissues, such as a suspension culture of cells or embryogeniccallus or alternatively one may transform immature embryos or otherorganized tissue directly. In this technique, one would partiallydegrade the cell walls of the chosen cells by exposing them topectin-degrading enzymes (pectolyases) or mechanically wound tissues ina controlled manner.

An efficient method for delivering transforming DNA segments to plantcells is microprojectile bombardment. In this method, particles arecoated with nucleic acids and delivered into cells by a propellingforce. Exemplary particles include those comprised of tungsten,platinum, and preferably, gold. For the bombardment, cells in suspensionare concentrated on filters or solid culture medium. Alternatively,immature embryos or other target cells may be arranged on solid culturemedium. The cells to be bombarded are positioned at an appropriatedistance below the macroprojectile stopping plate.

An illustrative embodiment of a method for delivering DNA into plantcells by acceleration is the Biolistics Particle Delivery System, whichcan be used to propel particles coated with DNA or cells through ascreen, such as a stainless steel or Nytex screen, onto a surfacecovered with target cells. The screen disperses the particles so thatthey are not delivered to the recipient cells in large aggregates.Microprojectile bombardment techniques are widely applicable, and may beused to transform virtually any plant species.

Agrobacterium-mediated transfer is another widely applicable system forintroducing gene loci into plant cells. An advantage of the technique isthat DNA can be introduced into whole plant tissues, thereby bypassingthe need for regeneration of an intact plant from a protoplast. ModernAgrobacterium transformation vectors are capable of replication in E.coli as well as Agrobacterium, allowing for convenient manipulations(Klee et al., Nat. Biotechnol., 3(7):637-642, 1985). Moreover, recenttechnological advances in vectors for Agrobacterium-mediated genetransfer have improved the arrangement of genes and restriction sites inthe vectors to facilitate the construction of vectors capable ofexpressing various polypeptide coding genes. The vectors described haveconvenient multi-linker regions flanked by a promoter and apolyadenylation site for direct expression of inserted polypeptidecoding genes. Additionally, Agrobacterium containing both armed anddisarmed Ti genes can be used for transformation.

In those plant strains where Agrobacterium-mediated transformation isefficient, it is the method of choice because of the facile and definednature of the gene locus transfer. The use of Agrobacterium-mediatedplant integrating vectors to introduce DNA into plant cells is wellknown in the art (Fraley et al., Nat. Biotechnol., 3:629-635, 1985; U.S.Pat. No. 5,563,055).

Transformation of plant protoplasts also can be achieved using methodsbased on calcium phosphate precipitation, polyethylene glycol treatment,electroporation, and combinations of these treatments (see, for example,Potrykus et al., Mol. Gen. Genet., 199:183-188, 1985; Omirulleh et al.,Plant Mol. Biol., 21(3):415-428, 1993; Fromm et al., Nature,312:791-793, 1986; Uchimiya et al., Mol. Gen. Genet., 204:204, 1986;Marcotte et al., Nature, 335:454, 1988). Transformation of plants andexpression of foreign genetic elements is exemplified in Choi et al.(Plant Cell Rep., 13:344-348, 1994), and Ellul et al. (Theor. Appl.Genet., 107:462-469, 2003).

A number of promoters have utility for plant gene expression for anygene of interest including but not limited to selectable markers,scoreable markers, genes for pest tolerance, disease resistance,nutritional enhancements and any other gene of agronomic interest.Examples of constitutive promoters useful for plant gene expressioninclude, but are not limited to, the cauliflower mosaic virus (CaMV)P-35S promoter, which confers constitutive, high-level expression inmost plant tissues (see, for example, Odel et al., Nature, 313:810,1985), including in monocots (see, for example, Dekeyser et al., PlantCell, 2:591, 1990; Terada and Shimamoto, Mol. Gen. Genet., 220:389,1990); a tandemly duplicated version of the CaMV 35S promoter, theenhanced 35S promoter (P-e35S); the nopaline synthase promoter (An etal., Plant Physiol., 88:547, 1988); the octopine synthase promoter(Fromm et al., Plant Cell, 1:977, 1989); the figwort mosaic virus(P-FMV) promoter as described in U.S. Pat. No. 5,378,619; an enhancedversion of the FMV promoter (P-eFMV) where the promoter sequence ofP-FMV is duplicated in tandem; the cauliflower mosaic virus 19Spromoter; a sugarcane bacilliform virus promoter; a commelina yellowmottle virus promoter; and other plant virus promoters known to expressin plant cells.

A variety of plant gene promoters that are regulated in response toenvironmental, hormonal, chemical, or developmental signals can also beused for expression of an operably linked gene in plant cells, includingpromoters regulated by (1) heat (Callis et al., Plant Physiol., 88:965,1988), (2) light (e.g., pea rbcS-3A promoter, Kuhlemeier et al., PlantCell, 1:471, 1989; maize rbcS promoter, Schaffner and Sheen, Plant Cell,3:997, 1991; or chlorophyll a/b-binding protein promoter, Simpson etal., EMBO J., 4:2723, 1985), (3) hormones, such as abscisic acid(Marcotte et al., Plant Cell, 1:969, 1989), (4) wounding (e.g., wunl,Siebertz et al., Plant Cell, 1:961, 1989); or (5) chemicals, such asmethyl jasmonate, salicylic acid, or Safener. It may also beadvantageous to employ organ-specific promoters (e.g., Roshal et al.,EMBO J., 6:1155, 1987; Schernthaner et al., EMBO J., 7:1249, 1988;Bustos et al., Plant Cell, 1:839, 1989).

Exemplary nucleic acids which may be introduced to plants of thisinvention include, for example, DNA sequences or genes from anotherspecies, or even genes or sequences which originate with or are presentin the same species, but are incorporated into recipient cells bygenetic engineering methods rather than classical reproduction orbreeding techniques. However, the term “exogenous” is also intended torefer to genes that are not normally present in the cell beingtransformed, or perhaps simply not present in the form, structure, etc.,as found in the transforming DNA segment or gene, or genes which arenormally present and that one desires to express in a manner thatdiffers from the natural expression pattern, e.g., to over-express.Thus, the term “exogenous” gene or DNA is intended to refer to any geneor DNA segment that is introduced into a recipient cell, regardless ofwhether a similar gene may already be present in such a cell. The typeof DNA included in the exogenous DNA can include DNA which is alreadypresent in the plant cell, DNA from another plant, DNA from a differentorganism, or a DNA generated externally, such as a DNA sequencecontaining an antisense message of a gene, or a DNA sequence encoding asynthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and couldpotentially be introduced into a tomato plant according to theinvention. Non-limiting examples of particular genes and correspondingphenotypes one may choose to introduce into a tomato plant include oneor more genes for insect tolerance, such as a Bacillus thuringiensis(B.t.) gene, pest tolerance such as genes for fungal disease control,herbicide tolerance such as genes conferring glyphosate tolerance, andgenes for quality improvements such as yield, nutritional enhancements,environmental or stress tolerances, or any desirable changes in plantphysiology, growth, development, morphology or plant product(s). Forexample, structural genes would include any gene that confers insecttolerance including but not limited to a Bacillus insect control proteingene as described in WO 99/31248, herein incorporated by reference inits entirety, U.S. Pat. No. 5,689,052, herein incorporated by referencein its entirety, U.S. Pat. Nos. 5,500,365 and 5,880,275, hereinincorporated by reference in their entirety. In another embodiment, thestructural gene can confer tolerance to the herbicide glyphosate asconferred by genes including, but not limited to Agrobacterium strainCP4 glyphosate resistant EPSPS gene (aroA:CP4) as described in U.S. Pat.No. 5,633,435, herein incorporated by reference in its entirety, orglyphosate oxidoreductase gene (GOX) as described in U.S. Pat. No.5,463,175, herein incorporated by reference in its entirety.

Alternatively, the DNA coding sequences can affect these phenotypes byencoding a non-translatable RNA molecule that causes the targetedinhibition of expression of an endogenous gene, for example viaantisense- or cosuppression-mediated mechanisms (see, for example, Birdet al., Biotech. Gen. Engin. Rev., 9:207, 1991). The RNA could also be acatalytic RNA molecule (i.e., a ribozyme) engineered to cleave a desiredendogenous mRNA product (see, for example, Gibson and Shillito, Mol.Biotech., 7:125,1997). Thus, any gene which produces a protein or mRNAwhich expresses a phenotype or morphology change of interest is usefulfor the practice of the present invention.
